Please will you show us what you've already tried? Have you looked into PIVOT?

OK, so the requirement has changed a little. You now need to concatenate the values into a string rather than having each as a separate column in the same row. If you are using SQL Server 2017 or later, you can use the STRING_AGG aggregate function, otherwise I recommend that you try the FOR XML technique described in this article.
